[1704.08803] Neural Ranking Models with Weak Supervision (2017)(About) Main Idea: To leverage large amounts of unsupervised data to infer “weak” labels and use that signal for learning supervised models as if we had the ground truth labels. See [blog post](/doc/?uri=http%3A%2F%2Fmostafadehghani.com%2F2017%2F04%2F23%2Fbeating-the-teacher-neural-ranking-models-with-weak-supervision%2F)
A Tri-Partite Neural Document Language Model for Semantic Information Retrieval (2018 - ESWC conference)(About) from the abstract: Previous work in information retrieval have shown that using evidence, such as concepts and relations, from external knowledge sources could enhance the retrieval performance... This paper presents a new tri-partite neural document language framework that leverages explicit knowledge to jointly constrain word, concept, and document learning representations to tackle a number of issues including polysemy and granularity mismatch.
Retrofitting Word Vectors to Semantic Lexicons (2014)(About) Method for refining vector space representations using relational information from semantic lexicons **by encouraging linked words to have similar vector representations**, and it makes no assumptions about how the input vectors were constructed.
Graph-based learning technique for using lexical relational resources to obtain higher quality semantic vectors, which we call “retrofitting.” Retrofitting is applied as a **post-processing step** by running belief propagation on a graph constructed from lexicon-derived relational information to update word vectors. This allows retrofitting to be used on pre-trained word vectors obtained using any vector training model.
Knowledge Graph and Text Jointly Embedding (2014)(About) method of jointly embedding knowledge graphs and a text corpus so that entities and words/phrases are represented in the same vector space.
Promising improvement in the accuracy of predicting facts, compared to separately embedding knowledge graphs and text (in particular, enables the prediction of facts containing entities out of the knowledge graph)

Combining word and entity embeddings for entity linking (ESWC 2017)(About) The general approach for the entity linking task is to generate, for a given mention, a set of candidate entities from the base and, in a second step, determine which is the best
one. This paper proposes a novel method for the second step which is
based on the **joint learning of embeddings for the words in the text and
the entities in the knowledge base**.
Poincaré Embeddings for Learning Hierarchical Representations(About) > While complex symbolic datasets often exhibit a latent hierarchical structure, state-of-the-art methods typically learn embeddings in Euclidean vector spaces, which do not account for this property. For this purpose, we introduce a new approach for learning hierarchical representations of symbolic data by embedding them into hyperbolic space
