+= Geolexica now has Reverse Semantic Search
+
+== Introduction
+
+Ever forgotten a specific word but could describe its meaning?
+
+Internet search engines more than often return unrelated entries.
+The solution is *reverse semantic search*: given an input of the meaning of the
+word (search phrase), provide an output with dictionary words that match the
+meaning.
+The key to accurate reverse search lies in the machine's ability to understand
+semantics.
+We employ deep learning approaches in natural language processing (NLP) to
+enable better comparison of meanings between the search phrases with word
+definitions.
+Accuracy will be significantly increased.
+The project outcome will be employed on Geolexica as a pilot application and
+testbed for evaluation.
+The ability to identify entities with similar semantics facilitates ontology
+discovery in the Semantic Web and in Technical Language Processing (TLP).
