    1. System for semantic interpretation

      A semantic database is generated to provide answers to questions by users. Text processors can receive text from text sources, and can convert the text into intermediate logical statements. The text processors can then convert these statements into unambiguous semantic representations. A semantic database connected to the text processors can store the semantic representations. Query processors connected to the semantic database can receive a question from a computing device operated by a user, and can convert the question into intermediate logical subqueries. The query processors can then use a disambiguation table to generate unambiguous semantic subqueries from these intermediate logical ...

    6. On-page SEO in 2017: Optimizing for RankBrain & Semantic Search -

      2.3K #growthhacks #localseo #seo We've been hearing about "semantic search" since Google's Hummingbird update back in 2013. Now, Google's leveraging it in numerous ways: the Knowledge Graph, RankBrain, LSI, natural language processing algorithms... In today's post on 5 major aspects of semantic search (and their implications for SEO), I'm doing my best to explain how semantic search works and what you need (and don't need!) to change in your strategy to grow rankings in 2017.

    9. Techniques for understanding the aboutness of text based on semantic analysis

      In one embodiment of the present invention, a semantic analyzer translates a text segment into a structured representation that conveys the meaning of the text segment. Notably, the semantic analyzer leverages a semantic network to perform word sense disambiguation operations that map text words included in the text segment into concepts--word senses with a single, specific meaning--that are interconnected with relevance ratings. A topic generator then creates topics on-the-fly that includes one or more mapped concepts that are related within the context of the text segment. In this fashion, the topic generator tailors the semantic network to the text segment ...

    10. Converting a text sentence to a series of images

      A text sentence is automatically converted to an image sentence that conveys semantic roles of the text sentence. This is accomplished by identifying semantic roles associated with each verb of a sentence, any associated verb adjunctions, and identifying the grammatical dependencies between words and phrases in a sentence, in some embodiments. An image database, in which each image is tagged with descriptive information corresponding to the image depicted, is queried for images corresponding to the semantic roles of the identified verbs. Unless a single image is found to depict every semantic role, the text sentence is split into two smaller ...

      Natural language processing (sentiment classification) API for French text

      Good point about the influence of the lexicon on classifier accuracy. You're right, the topic of the corpus I have is esoteric, so a conventional lexicon would perform poorly. – Escher Apr 12 '15 at 21:21 up vote 1 down vote Semantics is a difficult topic in NLP... Stanford has some great NLP tools that I suggest you take a look at, though they don't have anything for semantic analysis as far as I can tell. If this is for a large, ongoing project I implore you to write your own classifier!
