Center node: "analysis of wikipedia based corpora for question answering"
  Abstract: This paper gives comprehensive analyses of corpora based on Wikipedia for several tasks in question answering. Four recent corpora are collected,WikiQA, SelQA, SQuAD, and InfoQA, and first analyzed intrinsically by contextual similarities, question types, and answer categories. These corpora are then analyzed extrinsically by three question answering tasks, answer retrieval, selection, and triggering. An indexing-based method for the creation of a silver-standard dataset for answer retrieval using the entire Wikipedia is also presented. Our analysis shows the uniqueness of these corpora and suggests a better use of them for statistical question answering learning.

Connected through hyperedge HE-1 (induced by source paper "wsd algorithm based on a new method of vector word contexts proximity calculation via epsilon filtration"):

    - "calculated attributes of synonym sets"
    - "linking imagenet wordnet synsets with wikidata"
    - "texts in meaning out neural language models in semantic similarity task for russian"
