[Dbpedia-gsoc] GSoC 2015 - Introduction (Mingzhe)
Hi everyone, My name is Mingzhe. I am a PhD student at the University of South Carolina. My work mainly focuses on Natural Language Processing and NLP related web development. I am the principle developer of Wikitheoria.com [1], an NSF sponsored web-based crowd-sourcing tool to share and collaborate on sociological researchable ideas. The ultimate goal of this project is to contribute the well-structured sociology information and knowledge to our Linked Data community. I am proficient in Python, Java at the back-end, Javascript and jQuery at the front-end. I have also been using NodeJS, angularJS and MongoDB during my development at HelpMonger.com [2]. I am particularly interested in project idea *5.10 DBpedia Metadata Datasets*. I have some experience on RDF and SPARQL during the course study of Natural Language Processing and Service Oriented Computing. I believe this project will help me gain more experience and knowledge that I could apply to Wikitheoria in the future. I have submitted my proposal on http://www.google-melange.com/. Hoping to work with you soon.

Hi Shashank, It looks alright. I think you can skip the Spark part, as you are not interested in the project concerning the model building. As for the specific project you selected I think best would be to: - Understand how a spotlight model is divided (Surface form store, Context Store, Candidate Store). Probably this blog [1] entry can help you as well as playing with [2] - Also reading the main paper on which spotlight is based on (I previously mentioned it but it is also mentioned in the literature at github) [1] http://engineering.idioplatform.com/2015/02/23/spotlight-model-editor.html [2] https://github.com/idio/spotlight-model-editor On Thu, Mar 12, 2015 at 1:35 PM, shashank juyal sjuyal...@gmail.com wrote: Hi David, Please find attached the warm up tasks I have done.

Re: [Dbpedia-gsoc] GSoC 2015 - Introduction
Hi Guido, Dimitris already gave you some hints on bugs/features you can be working on. What I can give you are some general tasks regarding to topic 5.5 Improving the Mappings Wiki (5.4 has similar requirements): There are 2 main components you will be working with, the dbpedia mappings wiki and the server component of the extraction framework. The mappings wiki is a modified version of Mediawiki. It stores the mappings between Mediawiki Templates and DBpedia Classes/properties. Each template is mapped onto a dbpedia class and each property in the template is mapped onto a dbpedia ontology property. Whenever an editor saves a mapping he has the option of validating it. This option is presented as a validate button besides the save button. By clicking this button a service call is executed to the Server component of the DBpedia Extraction Framework. When the call is made the contents of the mediawiki article are passed to the server, the server then analyzes if the text conforms to the dbpedia mappings syntax and validates it. If it passes the validation the mappings wiki tells the editor his mapping is valid, otherwise not valid. Of course the mappings wiki does more things but this is just go get a quick idea. I can give you 2 fast warm-up tasks with more to follow: 1) Create a mediawiki extension [1] that hooks into the create/edit workflow of mediawiki [2] , you will use the necessary hooks for that. Insert another button besides save that calls a rest web service. 2) Get the server module of the extraction framework up and running and experiment with it.

Re: [Dbpedia-gsoc] GSoC 2015 Introduction and Parallel processing in DBpedia extraction Framework
Yup, looking at the changelog of Apache Spark and having worked on upgrading much smaller applications across Spark versions, I can attest that this process shouldn't take too much time. The number of breaking changes are very minimal in recent versions. An idea I had, which I would like feedback on is having a configuration picker, rather than a list of preconfigured container/images. Kind of along the lines of Fedora's Revisor project [1]. You could mix and match depending on the configuration you want to use and a customized image/container is created for you. Of course, the feasibility of this is an open question... Honestly, if you ask me, this one project could probably be broken up into multiple projects, each with a different end goal. Docker brings in a very interesting set of things to play with, and it would be great if some of the mentors could provide more feedback on what the end goal of this specific GSoC project is. :) Thanks [1] http://revisor.fedoraunity.org/ Hi Xiao, and welcome! Some thoughts from my initial impression and I appreciate your feedback: ?- The project ?uses?? ?spark 0.9.1 while the latest version? of spark? is bumped to 1.2.1.? I suppose there will be some work on upgrade it to the new version.? It'll perhaps be good to port the code to Spark 1.2.1; I can't imagine it'll take too much work because the Spark API has been pretty stable since that. - It looks like the process is putting the data into HDFS, using spark the exact data and writing result back to HDFS. ?Are there any design document for this project? Yes, but it can also work without HDFS. On a single-node cluster you can write directly to the file system (I'm not sure if there is enough documentation on that, but there should be; it's mostly about substituting hdfs:///home/user/blah with file:///home/user/blah). On a multi-node cluster with NFS you can also work without HDFS. I have been meaning to write a proper paper on the project since a few months but never managed to get around to it. - Spark can works with various distributed file system (S3, GlusterFS, etc) not limited to HDFS. So I suppose this could be configurable. It'd be a good idea to make this configurable, and I suppose it fits in well with the docker containers idea too. Different kinds of configurations for EC2/S3, Google Cloud etc. Feel free to ask any other questions that you may have while running it.

Hi Shashank, On DBpedia Spotlight – Better Context Vectors: Here are the DBPedia Spotlight warm tasks: https://github.com/dbpedia-spotlight/dbpedia-spotlight/wiki/Warm-up-tasks if you take a look at the github issue page you should find some of the problems we are dealing with. One of the ideas could be experimenting with word2vec. Have a nice weekend :) On Sat, Mar 7, 2015 at 11:46 AM, shashank juyal sjuyal...@gmail.com wrote: Hi, I am a Masters student in International Institute of Information technology, Hyderabad (IIIT-H). I am interested in taking part in this year's GSOC. Many of the projects in DBPedia sounds very familiar and interesting to me as I have worked closely with many of the concepts and technologies used in the project. I have worked previously with Wikipedia data and built a small search over it based on tf-idf score and my own parser. Also currently I am working in a project Question Answer techniques using NLP which uses concepts like wordtovec, CBOW, NL Processing and translation to query language, which are mentioned in some of the projects in DBPedia-Spotlight. Based on this, I would like to work on the following projects: 1) Fact Extraction from Wikipedia Text 2) Keyword Search on DBpedia 3) Deploying a DBpedia Question Answering Engine 4) DBpedia Spotlight – Better Context Vectors Please let me know the warm-up tasks in the above projects.

Re: [Dbpedia-gsoc] GSoC 2015 Introduction and Parallel processing in DBpedia extraction Framework
Hi Xiao, and welcome! Some thoughts from my initial impression and I appreciate your feedback: - The project uses spark 0.9.1 while the latest version of spark is bumped to 1.2.1. I suppose there will be some work on upgrade it to the new version. It'll perhaps be good to port the code to Spark 1.2.1; I can't imagine it'll take too much work because the Spark API has been pretty stable since that. - It looks like the process is putting the data into HDFS, using spark the exact data and writing result back to HDFS. Are there any design document for this project? Yes, but it can also work without HDFS. On a single-node cluster you can write directly to the file system (I'm not sure if there is enough documentation on that, but there should be; it's mostly about substituting hdfs:///home/user/blah with file:///home/user/blah). On a multi-node cluster with NFS you can also work without HDFS. I have been meaning to write a proper paper on the project since a few months but never managed to get around to it. - Spark can works with various distributed file system (S3, GlusterFS, etc) not limited to HDFS. So I suppose this could be configurable. It'd be a good idea to make this configurable, and I suppose it fits in well with the docker containers idea too. Different kinds of configurations for EC2/S3, Google Cloud etc. Feel free to ask any other questions that you may have while running it.

[Dbpedia-gsoc] [GSOC 2015] Introduction and Help in starting the contribution
Hi Everybody, I am Nurendra Choudhary from International Institute of Information Technology, Hyderabad, India [1] and doing my major in Computational Linguistics. My interests lie in Natural Language Processing, Artificial Intelligence and Machine Learning. I like coding in Python, C, C++. Here's my SourceForge[2] and Github[3] profile. I normally go by the name akirato when doing projects or any coding. I went through the Ideas Page for GSOC 2015 and am really interested in the Fact Extraction from Wikipedia Text project. I have some ideas on the project. Like maybe, the first step could be to find the relation between verbs and the rest of the parts (something like theta roles, maybe) which further can be developed to finding relation between all pairs of words and so on. I have setup the development environment with Eclipse. Could you help me in proceeding further with the necessities required for the project?
