The 10 Biggest Issues in Natural Language Processing NLP

natural language processing problems

NLP is data-driven, but which kind of data and how much of it is not an easy question to answer. Scarce and unbalanced, as well as too heterogeneous data often reduce the effectiveness of NLP tools. However, in some areas obtaining more data will either entail more variability (think of adding new documents to a dataset), or is impossible (like getting more resources for low-resource languages). Besides, even if we have the necessary data, to define a problem or a task properly, you need to build datasets and develop evaluation procedures that are appropriate to measure our progress towards concrete goals. Relationship extraction is a revolutionary innovation in the field of natural language processing…

In case of syntactic level ambiguity, one sentence can be parsed into multiple syntactical forms. Lexical level ambiguity refers to ambiguity of a single word that can have multiple assertions. Each of these levels can produce ambiguities that can be solved by the knowledge of the complete sentence. The ambiguity can be solved by various methods such as Minimizing Ambiguity, Preserving Ambiguity, Interactive Disambiguation and Weighting Ambiguity [125]. Some of the methods proposed by researchers to remove ambiguity is preserving ambiguity, e.g. (Shemtov 1997; Emele & Dorna 1998; Knight & Langkilde 2000; Tong Gao et al. 2015, Umber & Bajwa 2011) [39, 46, 65, 125, 139]. They cover a wide range of ambiguities and there is a statistical element implicit in their approach.

Information extraction is concerned with identifying phrases of interest of textual data. For many applications, extracting entities such as names, places, events, dates, times, and prices is a powerful way of summarizing the information relevant to a user’s needs. In the case of a domain specific search engine, the automatic identification of important information can increase accuracy and efficiency of a directed search. There is use of hidden Markov models (HMMs) to extract the relevant fields of research papers. These extracted text segments are used to allow searched over specific fields and to provide effective presentation of search results and to match references to papers. For example, noticing the pop-up ads on any websites showing the recent items you might have looked on an online store with discounts.

Also, NLP has support from NLU, which aims at breaking down the words and sentences from a contextual point of view. Finally, there is NLG to help machines respond by generating their own version of human language for two-way communication. Natural Language Processing is a subfield of Artificial Intelligence capable of breaking down human language and feeding the tenets of the same to the intelligent natural language processing problems models. Emotion   Towards the end of the session, Omoju argued that it will be very difficult to incorporate a human element relating to emotion into embodied agents. On the other hand, we might not need agents that actually possess human emotions. Stephan stated that the Turing test, after all, is defined as mimicry and sociopaths—while having no emotions—can fool people into thinking they do.

Higher-level NLP applications

Social data is often information directly created by human input and this data is unstructured in nature, making it nearly impossible to leverage with standard SQL. NLP can make sense of the unstructured data that is produced by social data sources and help to organize it into a more structured model to support SQL-based queries. NLP opens the door for sophisticated analysis of social data and supports text data mining and other sophisticated analytic functions. Cross-lingual representations   Stephan remarked that not enough people are working on low-resource languages.

These new tools will transcend traditional business intelligence and will transform the nature of many roles in organizations — programmers are just the beginning. Many sectors, and even divisions within your organization, use highly specialized vocabularies. Through a combination of your data assets and open datasets, train a model for the needs of specific sectors or divisions.
