Recognyze Entity Extraction

Which airlines have a positive reputation among social media users? Who are the most visible CEOs in the computer industry, and what are mainstream media associating with them? Recognyze helps to answer such questions. It identifies named entities (locations, events, persons, organizations, etc.) in text documents from online media and corporate knowledge archives, and aligns these entities with external knowledge sources – e.g., items contained in linked open data archives.

Analyzing Business Networks. The result is a comprehensive and continuously evolving repository of actionable knowledge. This repository enables decision support services that help to better understand business networks and dynamic relations [1] among their actors – e.g. by automatically distinguishing common relation types such as competitor, customer, supplier and owner. Research has shown that an analysis of such business networks provides new insights for measuring performance and evaluating competitive advantage [2]. It can help estimate the bargaining power of enterprises over their customers and suppliers, for example, the intensity of rivalry, the threat of substitute products, or the expected impact of new market entrants [3].

Extracting Knowledge from Online Sources. Properly collected and processed, news media coverage and user-generated content from social media platforms are valuable sources of feedback that help to optimize communication strategies, marketing campaigns, and product development activities. Leveraging the full economic potential of these sources requires a seamless integration of factual (concepts, instances, relations) and affective (beliefs, opinions, arguments, etc.) knowledge:

  • Affective Knowledge includes sentiment and other emotions expressed in a document, which are captured and evaluated by webLyzard’s opinion mining algorithms [4].
  • Factual Knowledge. Complementing these algorithms, the Recognyze entity extraction component focuses on facts as the second pillar of Web intelligence, within and across organizational boundaries. It not only identifies and classifies entities, but also grounds them to external knowledge bases such as DBpedia and Freebase, or to corporate databases.

Accessing Recognyze. Users can inspect annotated content elements via the metadata view of the webLyzard dashboard. For developers and application providers, we provide demo access to the Recognyze REST API for up to 100 queries per day upon request.
