The TextWise Semantic Cloud provides an API for clients and users to actively engage with our core technology - Semantic Signatures. See our Semantic Signatures used for Similarity Search, Categorization, and Concept Tagging in action by trying the demo.
The features of the SemanticHacker API include the following:
Semantic Signatures
The SemanticHacker API provides a signature service call that analyzes the text or web page provided in the call and returns a Semantic Signature. Semantic Signatures are a unique way of representing and analyzing multiple concepts and topics in text.They can be constructed for a wide range of texts including individual words, phrases, word-lists (e.g. metadata), short passages (such as text advertisements or image labels), web pages, or full text documents (e.g. technical articles).
Learn more about the Semantic Signatures service available through the API.
Similarity Search for Content Matching
The TextWise SemanticHacker API provides a match service call that analyzes the text or Web page provided in the call and returns a match. Instead of using the terms contained in the text and their frequencies, SemanticHacker API matching uses the dimensions in the document's Semantic Signature and their associated weights. The operation can be viewed as determining the distance between the Semantic Signatures of an item and an entire collection. Learn more about the Similarity Search service available through the API.
Categorization
The SemanticHacker API category service call identifies the main topic categories for the input text or URI, ordered by weight. Categorization of content is performed by analyzing the dimensions and weights of the provided content's Semantic Signature and identifying those dimensions that are most relevant to the Signature. If you have a small data set and prefer high-level categories, use our category tags. If you have a large data set and prefer a more refined distinction, use the top dimension to categorize.
Learn more about the Categorization service available through the API.
Concept Tags
The SemanticHacker API concept service call can be leveraged to generate machine readable and displayable tags for content navigation.These tags are very specific terms which are derived from the content’s Semantic Signature, a semantic dictionary and the original text. Each tag is accompanied by a weight that describes the relevance of that term to the content. Concept tags are generated by obtaining a list of words that appear in both the semantic dictionary and the content text for the highest weighted semantic dimensions of the text.

Widget & WordPress Plugin
We've created a WordPress Plugin (for bloggers) and a Widget (for content publishers) to enable you to use Similarity Search right away on your blog or Web site, without requiring any programming skills. The WordPress plugin requires a free token obtained by registering for a SemanticHacker API account.
