A Text Wikification System is a text annotation system that implements a text wikification algorithm to solve a text wikification task.
- AKA: Wikifier.
- Context:
- It can be supported by:
- It can range from being a General Knowledge-based Wikification System to being a Domain-Specific Wikification System.
- It can range from (typically) being a Same-Language Wikification System to being a Cross-Language Wikification System.

- … Entity linking requires a knowledge base containing the entities to which entity mentions can be linked. A popular choice for entity linking on open domain text are knowledge-bases based on Wikipedia,[1] [2] in which each page is regarded as a named entity. NED using Wikipedia entities has been also called wikification (see Wikify! an early entity linking system[3] ). A knowledge base may also be induced automatically from training text [4] or manually built. (...)

- QUOTE: Contextual disambiguation and grounding of concepts and entities in natural language text are essential to moving forward in many natural language understanding related tasks and are fundamental to many applications. The Wikification task (Bunescu and Pasca, 2006; Mihalcea and Csomai, 2007; Ratinov et al., 2011) aims at automatically identifying concept mentions appearing in a text document and link it to (or “ground it in”) a concept referent in a knowledge base (KB) (e.g., Wikipedia). For example, consider the sentence, "The Times report on Blumental (D) has the potential to fundamentally reshape the contest in the Nutmeg State.", a Wikifier should identify the key entities and concepts (Times, Blumental, D and the Nutmeg State), and disambiguate them by mapping them to an encyclopedic resource revealing, for example, that “D” here represents the Democratic Party, and that “the Nutmeg State” refers Connecticut.

- QUOTE: Wikification (D2W), the task of identifying concepts and entities in text and disambiguating them into their corresponding Wikipedia page(...)
Given a document D containing a set of concept and entity mentions M (referred to later as surface), the goal of Wikification is to find the most accurate mapping from mentions to Wikipedia titles T; this mapping needs to take into account our understanding of the text as well as background knowledge that is often needed to determine the most appropriate title. We also allow a special NIL title that captures all mentions that are outside Wikipedia.

- QUOTE: Wikification is the task of identifying and linking expressions in text to their referent Wikipedia pages(...) Previous studies on Wikification differ with respect to the corpora they address and the subset of expressions they attempt to link. For example, some studies focus on linking only named entities, whereas others attempt to link all “interesting” expressions, mimicking the link structure found in Wikipedia. Regardless, all Wikification systems are faced with a key Disambiguation to Wikipedia (D2W) task. In the D2W task, we’re given a text along with explicitly identified substrings (called mentions) to disambiguate, and the goal is to output the corresponding Wikipedia page, if any, for each mention. For example, given the input sentence “I am visiting friends in <Chicago>,” we output http://en.wikipedia.org/wiki/Chicago – the Wikipedia page for the city of Chicago, Illinois, and not (for example) the page for the 2002 film of the same name.

Automatic text wikification implies solutions for the two main tasks performed by a Wikipedia contributor when adding links to an article: (1) keyword extraction, and (2) link disambiguation.

We designed and implemented a system that solves the “text wikification” problem in four steps, as illustrated in Figure 2.
