Mining Unstructured Data in Software Repositories
 
26:57
The amount of unstructured data available to software engineering researchers in versioning systems, issue trackers, achieved communications, etc is continuously growing over time. The mining of such data represents an unprecedented opportunity for researchers to investigate new research questions and to build a new generation of recommender systems supporting development and maintenance activities. This talk describes works on the application of Mining Unstructured Data (MUD) in software engineering. The talk briefly reviews the types of unstructured data available to researchers providing pointers to basic mining techniques to exploit them. Then, an overview of the existing applications of MUD in software engineering is provided with a specific focus on textual data present in software repositories and code components. The talk also discusses perils the "miner" should avoid while mining unstructured data and lists possible future trends for the field.

What is SOFTWARE REPOSITORY? What does SOFTWARE REPOSITORY mean? SOFTWARE REPOSITORY meaning - SOFTWARE REPOSITORY definition - SOFTWARE REPOSITORY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A software repository is a storage location from which software packages may be retrieved and installed on a computer. Many software publishers and other organizations maintain servers on the Internet for this purpose, either free of charge or for a subscription fee. Repositories may be solely for particular programs, such as CPAN for the Perl programming language, or for an entire operating system. Operators of such repositories typically provide a package management system, tools intended to search for, install and otherwise manipulate software packages from the repositories. For example, many Linux distributions use Advanced Packaging Tool (APT), commonly found in Debian based distributions, or yum found in Red Hat based distributions. There are also multiple independent package management systems, such as pacman, used in Arch Linux and equo, found in Sabayon Linux. As software repositories are designed to include useful packages, major repositories are designed to be malware free. If a computer is configured to use a digitally signed repository from a reputable vendor, and is coupled with an appropriate permissions system, this significantly reduces the threat of malware to these systems. As a side effect, many systems that have these capabilities do not require anti-malware software such as anti-virus software. Most major Linux distributions have many repositories around the world that mirror the main repository. A package management system is different from a package development process. A typical use of a package management system is to facilitate the integration of code from possibly different sources into a coherent stand-alone operating unit. Thus, a package management system might be used to produce a distribution of Linux, possibly a distribution tailored to a specific restricted application. A package development process, by contrast, is used to manage the co-development of code and documentation of a collection of functions or routines with a common theme, producing thereby a package of software functions that typically will not be complete and usable by themselves. A good package development process will help users conform to good documentation and coding practices, integrating some level of unit testing. The table below provides examples of package development processes.

scale.bythebay.io: Rajesh Muppalla, Continuous Delivery Principles for Machine Learning
 
33:05
Real world Software Engineering is an iterative process and one of its main objectives is to get changes all of types - including new features, configuration changes, bug fixes and experiments into production and into the hands of the users, safely, quickly and in a sustainable way. Continuous Delivery (CD), a software engineering discipline, with its principled approach allows you to solve this exact problem. The core idea of CD is to create a repeatable, reliable and incrementally improving process for taking software from concept to the end user. Like software development, building real world machine learning (ML) algorithms is an also an iterative process with a similar objective - How do I get my ML algorithms into production and in the hands of the users in a safe, quick and sustainable way. The current process of building models, testing and deploying them into production is at best an ad-hoc process in most companies. At Indix, while building the Google of Products, we have had some good success in combining the best practices of continuous delivery in building our machine learning pipelines using open source tools and frameworks. The talk will not focus on the theory of ML or about choosing the right ML algorithm but specifically on the last mile problem of taking models to production and the lessons learned while applying the concept of CD to ML.. Here are some of the key questions that the talk with try to answer. ML Models Repository as analogous to Software Artifacts Repository - Similar to a software repository, what are the features of a Models Repository to aid traceability and reproducibility? Specifically, how do you manage models end to end - managing model metadata, visualization and lineage etc? ML Pipelines to orchestrate and visualize the end to end flow - A typical ML workflow has multiple stages. How do you model your entire workflow as a pipeline (similar to Build Pipeline in CD) to automate the entire process and help visualize the entire end to end flow? Model Quality Assurance - What quality gates and evaluation metrics, either manual and automated, should be used before exporting (promoting) models for serving in production? What happens when several different models are in play? How do you measure the models individually and then also in combination Serving Models in Production - How do you serve and scale these models in production? What happens when these models are heterogenous (built using different languages - Scala, Python etc.)? Regression Testing of Models - When exporting a new models, whats the best way to compare the performance of the newer model to the one already deployed on real-world (production) data? Maintenance and Monitoring of Models in production - Deploying models to production is only half the job done. How do you measure the performance of your model while its running in production?

What is BUSINESS RULE MINING? What does BUSINESS RULE MINING mean? BUSINESS RULE MINING meaning - BUSINESS RULE MINING definition - BUSINESS RULE MINING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Business rule mining is the process of extracting essential intellectual business logic in the form of Business Rules from packaged or Legacy software applications, recasting them in natural or formal language, and storing them in a source rule repository for further analysis or forward engineering. The goal is to capture these legacy business rules in a way that the business can validate, control and change them over time. Business rule mining supports a Business rules approach, which is defined as a formal way of managing and automating an organization's business rules so that the business behaves and evolves as its leaders intend. It is also commonly conducted as part of an application modernization project evolving legacy software applications to service oriented architecture (SOA) solutions, transitioning to packaged software, redeveloping new in-house applications, or to facilitate knowledge retention and communication between business and IT professionals in a maintenance environment. Alternative approaches to rule mining are manual and automated. A manual approach involves the hand-writing of rules on the basis of subject matter expert interviews and the inspection of source code, job flows, data structures and observed behavior. Manually extracting rules is complicated by the difficulty of locating and understanding highly interdependent logic that has been interwoven into millions of lines of software code. An automated approach utilizes repository-based software to locate logical connections inherent within applications and extract them into a predetermined business rules format. With automation, an effective approach is to apply semantic structures to existing applications. By overlaying business contexts onto legacy applications, rules miners can focus effort on discovering rules from systems that are valuable to the business. Effort is redirected away from mining commoditized or irrelevant applications. Further, best practices coupled with various tool-assisted techniques of capturing programs’ semantics speeds the transformation of technical rules to true business rules. Adding business semantics to the analysis process allows users to abstract technical concepts and descriptors that are normal in an application to a business level that is consumable by a rules analyst. System integrators, software vendors, rules mining practitioners, and in-house development teams have developed technologies, proprietary methodologies and industry-specific templates for application modernization and business rule mining.

Mining Input Grammars with AUTOGRAM (Demo)
 
04:02
Live demo of the AUTOGRAM grammar miner Knowledge about how a program processes its inputs can help to understand the structure of the input as well as the structure of the program. In a JSON value like [1,true,"Alice"], for instance the integer value 1, the boolean value true and the string value "Alice" would be handled by different functions or stored in different variables. Our AUTOGRAM tool uses dynamic tainting to trace the data flow of each input character for a set of sample inputs and identifies syntactical entities by grouping input fragments that are handled by the same functions. The resulting context-free grammar reflects the structure of valid inputs and can be used for reverse engineering of formats and can serve as direct input for test generators. For more details on AUTOGRAM, see its project page at https://www.st.cs.uni-saarland.de/models/autogram/

Neal Lathia - Mining smartphone sensor data with python
 
34:25
PyData London 2016 Data from smartphone sensors can be used to learn from and analyse our daily behaviours. In this talk, I'll discuss processing and learning from sensor data with Python. I'll focus on accelerometers - a triaxial sensor that measures motion - starting with an overview pre-processing the data and ending with supervised and unsupervised learning applications and visualisations. Our smartphones are increasingly being built with sensors, that can measure everything from where we are (GPS, Wi-Fi) to how we move (accelerometers) and other aspects of our environments (e.g., temperature, humidity). Many apps are now being designed to collect and leverage this data, in order to provide interesting context-aware services and quantify our daily routines. In this talk, I'll give an overview of collecting sensor data from an Android app and processing the data with Python. I'll focus on accelerometers - a triaxial sensor that measures the device's motion - which is now being used in apps that detect what you are doing (cycling, running, riding a train); if we have enough time I'll also briefly cover a similar example with Wi-Fi/location data. Using an open-sourced Android app and iPython notebook, I'll discuss the following questions: What does the raw data look like? There are a number of trade-offs when collecting sensor data: most notably, data collection needs to be balanced against battery consumption. Plotting the raw data gives a view of how the data was sampled and how it changes across activities. How can I pre-process and extract features from this data? Three kinds of features can be extracted from acceleromter data: statistical, time-series, and signal-based. Most of these are readily available in well-known Python libraries (scipy, numpy, statsmodels). How can these features be used to analyse behaviours? I'll show an example of using accelerometer data to cluster users into groups, based on how active they are. How can these features be used to detect behaviours? I'll show an example of training a supervised learning algorithm (using scikit-learn) to detect walking vs. running vs. standing. I'll close by discussing how these techniques are being applied in novel smartphone apps for health monitoring. GitHub Repo: https://github.com/nlathia/pydata_2016

Scheduling Algorithm and GUI created for WEKA Bi-directional dataset for WEKA and 4D Simulation in a Virtual Environment Abstract — 4D scheduling and scheduling software databases/repositories in general are being utilized by many industries. The question of which algorithms to use for specific data mining solutions with regards to scheduling datasets and how much does the solution cost is a growing concern. In this paper the scheduling dataset created by the authors is a small example of a construction scheduling database by utilizing the WEKA open-source software. 4D simulations and the scheduling databases are very expensive when outsourcing to a proprietor like Microsoft Project and VICO Control vs. utilizing an open source free solution like WEKA. The authors objective is to show how to prepare and process 4D scheduling data for free and obtain similar results to those of an expensive proprietary software. Our goal is for the reader to attain new knowledge on how to create their own bi-directional dataset and visualization tool for free by utilizing open source application development kits.

Using a Fedora institutional repository to preserve rescued data in OSF projects
 
03:04
The Data Conservancy was introduced to Data Rescue Boulder through our long-time partner Ruth Duerr of Ronin Institute. Through our conversations, we recognized that Data Rescue Boulder has a need to process large number of rescued data sets and store them in more permanent homes. We also recognized that Data Conservancy along with Open Science Framework have the software infrastructure to support such activities and bring a selective subset of the rescued data into our own institutional repository. We chose the subset of data based on a selection from one of the Johns Hopkins University faculty members. This video shows how a Fedora-based institutional repository can be leveraged to provide preservation services for content stored within an OSF project. JHU has developed tools for exporting the business objects from the OSF as archival packages. When ingested into our institutional repository and represented as RDF linked data, repository services can reason about the content within OSF projects in support of preservation, data mining, and other value-add activities.

"The Incremental Commitment Spiral Model (ICSM)," Barry Boehm
 
01:02:29
Dec. 17, 2013: The Incremental Commitment Spiral Model (ICSM): Principles and Practices for Successful Systems and Software with ACM Fellow Dr. Barry Boehm, TRW Professor in the USC Computer Sciences and Industrial and Systems Engineering Departments. Moderated by Dr. Boehm's former doctoral student LiGuo Huang, Associate Professor of Computer Science and Engineering at Southern Methodist University. The Incremental Commitment Spiral Model (ICSM) extends the scope of the original spiral model for software development to cover the definition, development, and evolution of cyber-physical-human systems. It has been successfully applied to systems ranging from small e-services applications to complex cyber-physical-human systems of systems. It is not a one-size-fits-all process model, but uses four essential principles to determine whether, where, and when to use candidate common-case process elements (reuse-based, prototype-based, agile, architected agile, plan-driven, product-line, systems of systems, legacy-based, etc.). The four essential principles are (1) Stakeholder value-based system evolution; (2) Incremental commitment and accountability; (3) Concurrent multi-discipline engineering; and (4) Evidence and risk-based decisions. This presentation covers the four essential principles and their rationale; spiral, phased, concurrency, and process-element-decision process views; associated tools such as an Electronic Process Guide and the Winbook stakeholder win-win requirements negotiation system; and examples of successful ICSM use and pitfalls to avoid. (Based on a book co-authored by Barry Boehm, Jo Ann Lane, Supannika Koolmanojwong, and Richard Turner.)

BattleScribe - Creating a Repository
 
11:36
A quick tutorial on how to share the data files you create as a data repository so BattleScribe users can download them and create army lists. Please note, when hosting your repository on your own website, you need to upload the entire repository folder and it's contents together! I don't recommend manually changing the contents of the folder in any way (except re-creating it with the Data Indexer). Dropbox: http://www.dropbox.com Enable the Public folder: http://www.dropbox.com/help/16/en

Chemical text mining using OSCAR
 
00:54
OSCAR produces semantic annotation of chemistry documents. It uses natural-language processing to identify terms related to chemistry, which allows fast and efficient extraction of chemistry information. This video provides an overview of OSCAR. It shows the software being used to search PubMed abstracts, process them and then browse the results. http://www.omii.ac.uk/wiki/OSCAR

GrimoireLab: free software for software development analytics
 
16:08
Lightning talk at FOSDEM 2018. The talk explains how to analyze software development with GrimoireLab. It will show with simple code how easy it is to retrieve data from git, GitHub, and many other kinds of repositories. Then, with the same toolkit, the data will be organized in ElasticSearch indexes, visualized in actionable dashboards, Many free / open source software (FOSS) projects feature an open development model, with public software development repositories which anyone can browse. These repositories are normally used to find specific information, such a certain commit or a particular bug report. But they can also be mined to extract all relevant data, so that it can be analyzed to learn about any aspect of the project. This talk will explain the GrimoireLab method for doing that, which is based on organizing all that information in a database, which can be later analyzed. This approach allows for minimal impact on the project infrastructure, since data is retrieved only once, even if it later analyzed many times. It allows as well for efficiency and comfort when mining data for an analysis, since the results are readily available, databases can be shared and replicated at will, and queried them with any kind of tools is easy. The tools that retrieve information from the repositories are grouped in the GrimoireLab toolset. It includes mature, widely tested programs capable of extracting information from most repositories used by FOSS projects of any scale. Many of them are agnostic with respect to the database used, although currently ElasticSearch is the best supported. The produced databases can be exploited in several ways, of which two will be explained during the talk: using Python/Pandas to produce IPython/Jupyter Notebooks which analyze some aspect of the project; and using Python to feed a ElasticSearch cluster, with a Kibana front-end for visualizing in a flexible, powerful dashboard. The talk will explain the whole process from data retrieval to visualization. Some of the contents of the talk are described in detail in the online book GrimoireLab Tutorial.
