Reach Workshop – 23 November 2018

The REACH project aims to develop solution to avail the provision for high speed Internet access in rural India using unlicensed TV white space spectrum and designing the Geolocation database for it. With the wide increase of population and use of Internet in India, the efficient utilization and management of spectrum is needed. The utilization of TV white space spectrum is emerging as a best alternative to fulfill this need since there are many unused channel in TV spectrum due to migration from analog to digital transmission technology.

REACH final meeting / Workshop was held on 23rd November 2018 in Bangalore.

Following are the details of the workshop

Workshop on Theoretical Foundations of Computer Science

International Institute of Information Technology, Bangalore (IIIT-B) is organising a “Summer School on Theoretical Foundations of Computer Science” that is sponsored by Sonata Software Ltd. The aim of this school is to encourage and promote interest in theoretical foundations of computer science among students and researchers. We identify a few selected topics in theoretical computer science and aim to conduct lectures in a tutorial fashion, primarily aimed at students with a basic understanding of theoretical computer science. This five-day event also features a few invited talks given by researchers from both academia and industry. The focus of the tutorial-style lectures will be on the foundations of the selected topics and will aim to include problem solving/hands-on sessions. The invited talks will focus on the state-of-the-art research on these or related topics and their applications.

The topics that we aim to cover are from Approximation Algorithms, Parameterised Algorithms and Complexity, Cryptography, Program Analysis and Formal Methods, and Theoretical Foundations of Distributed Computing. Since each of the above topics is itself broad, we only seek to give a very brief overview of the subject, and additionally some deeper insights into specific sub topics that may reflect the research interests of the speakers.

Talk on “Bridging big data and qualitative methods in the social sciences”

Date: Jan 3rd 2018

Time: 2:15 PM

Location: TBD

Abstract: With the rise of social media, a vast amount of new primary research material has become available to social scientists, but the sheer volume and variety of this make it difficult to access through the traditional approaches: close reading and nuanced interpretations of manual qualitative coding and analysis. This work sets out to bridge the gap by developing semi-automated replacements for manual coding through a mixture of crowdsourcing and machine learning, seeded by the development of a careful manual coding scheme from a small sample of data. To show the promise of this approach, we attempt to create a nuanced categorisation of responses on Twitter to several cases of extreme circumstances.

Title: Inferencing in the Large: Towards Automation of Semantic Integration and Knowledge Representation of Open Data

Abstract: Data available on public domain especially though open data initiatives such as,, publish useful information on various aspects of government policies and administration. One could derive immense insights by semantically integrating such datasets across various domains. Semantic Integration involves extraction of common domains or themes that explain a collection of datasets by identifying unique resources for data values and relations amongst rows of data across these datasets using known or custom vocabularies and knowledge bases. The natural taxonomy and classification of the entities, instances and properties in the vocabularies allow for extraction of themes relevant to the datasets. Multiple research efforts have addressed the problem of semantic annotation of web tables and csv tables, which mainly involves interpreting tabular data by linking them to relevant vocabularies, however they have not focussed on the problem of semantic integration of tables. Linking Government Data is an active research interest. The current process to semantically link such datasets is largely manual and involves manual identification of vocabularies, classes and properties for each dataset, creating templates which will then automate the process of mapping the data to the identified vocabularies.
Our work presents two models, 1) the generation of semantically linked data for the open datasets using vocabularies from LOD cloud such as Dbpedia, YAGO,, UMBEL etc and 2) representing the data in an intuitive home-grown Knowledge Representation Framework called MWF (Many Worlds on a Frame), a framework loosely modelled on Kripke Semantics. MWF allows for rich representation of data across two aspects – the type hierarchy(is-a) relationship and the containment hierarchy(is-in) relationship supported by roles and associations to transform the open datasets into a web of semantically interlinked themes and their associations.

Title: Understanding  trust in mediation

Abstract: Intermediaries have always been a part of the society. It was individuals who played a role of broker to orchestrate and facilitate transactions between various parties. Click here for more

Title: Narratives Plot Comparison

Abstract: Narratives are extremely versatile way of telling imaginary or fictional and true or empirical incidents whereas expositions are simple and concise documentation based on true and well researched content. Writing narratives is not bounded by any style, it is limited by the author’s intention to entertain, his experience and effort to compose. A similar message can be conveyed in varying grades of style and illustrative cases and hence comparing two narratives and scoring their similarity is non-trivial. Narratives have two aspects the flow of events called the Fabula and the expression style called Discourse, both aspects affect the reading experience and the impact of the intention or message to be conveyed by the author. Our hypothesis is that two narratives can be compared by matching the verbs and nouns of events of each subject. Click here for more

Title: Framework for Mediation Driven Learning

Abstract: Learning is a complex process in which the learner experiences permanent and lasting changes in knowledge, behaviour, or ways of processing the world. Every learner is unique and learns and perceives things differently, at a different pace. In the classroom environment which is designed for an average student, same content is delivered to all the students in the same way. There is a fundamental flaw in designing the curriculum in this way for an average student, since there are virtually no students who fit into this category of average [1]. Hence, there is a need to address the individuality of the student for effective learning. A learning theory called as “Independent Learning” addresses this. Independent learning encourages and enables students to become self-directed in their learning experiences and to have more autonomy and control over their learning. In addition to this, it is found that learning is very effective where there is a collaboration with other learners. In our work, we propose the concept of “mediation driven learning” which builds upon the theories of independent learning and collaborative learning and uses the power of Web to mediate or facilitate learning. We create a framework for mediation driven learning where we get the learners and tutors together on one platform and provide a mediation algorithm that finds an optimal matching between the learners and tutors for a particular learning concept.

Title: Understanding the Marketplace of Opinions

Abstract: Our understanding of web has been evolving from that of a passive repository to a participatory socio-cognitive space, where human beings are participants rather than users of it. More than effecting the daily transactions this space has created a huge impact on how thoughts are shaping at individual level and also in a community. To be able to interpret how the society is transforming, it is very important to understand how the web is impacting the social cognition….Click here for more

Title: Semantic Summarization from User Generated Text Reports

Abstract:Text summarization is an active research area among Natural Language Processing research community. The community have been developed diverse paradigms for generating summary from long documents, even-though there is minimal effort on creating summary from large collection of short and noisy documents. Here, the short documents refers to user generated social media activity messages or any short reports which are generated as part of any closed domain. The proposed research aims to (semi-) automate the process of summary generation from a given set of short documents with more emphasis on the semantics of the document content. The research is initiated with a completely unsupervised techniques. The entire document collection is represented as an undirected graph of key phrases and later the graph clustering, graph centrality based measures and Markov Random Field based factor computation techniques are used to glean the important information. Further simple natural language generation techniques and natural language specific heuristics are applied to generate the candidate sentences for the final summary.

Open Discussion:

During the open discussion, all the participants will briefly share their individual views and comments on whether research pursuits have changed their approach in life towards achieving their passions or goals, and if yes, share their experiences.
