AlchemyAPI

AlchemyAPI (now part of IBM) provides cloud based text analytics services to support sentiment analysis, marketing, content discovery, business intelligence, and most tasks where natural language processing is needed. An on-site capability can also be provided if needed.

The capabilities offered by AlchemyAPI go beyond those most large organizations could build in-house, and not least because the training set used to model language is 250 times larger than Wikipedia. Innovative techniques using deep learning technologies (multi-layered neural networks) also go well beyond most of the competition, and AlchemyAPI distinguishes itself by using the technology for image recognition in addition to text analytics.

The functionality is broad and includes:

  • Named entity recognition for identifying people, places, companies, products and other named items.
  • Sentiment analysis with sophisticated capabilities such as negation recognition, modifiers, document level, entity, keyword and quotation level sentiment.
  • Keyword extraction to identify content topics.
  • Concept tagging, which is capable of identifying concepts not explicitly mentioned in a document.
  • Relation extraction where sentences are parsed into subject, action and object.
  • Text categorization to identify most likely categories.
  • Other functionality such as author extraction, language detection and text extraction.

Alchemy API was founded in 2005 and is based in Denver Colorado. Pricing plans for the cloud based services are based on transaction per day and start with a free Starter subscription.


Angoss KnowledgeREADER

KnowledgeREADER from Angoss is part of a broad suite of analytics tools and specifically addresses text analytics in the context of customer oriented and marketing applications. It majors on visual representation including dashboards for sentiment and text analysis, and also provides a somewhat unique map of the results of association mining to display words that tend to occur together.

Many of the advanced features make use of the embedded Lexalytics text analytics engine – widely recognized as one of the best in class. Entity, theme and topic extraction are supported along with decision and strategy trees for profiling, segmentation and predictive modelling. Sentiment analysis supports the visual graphing of sentiment trends and individual documents can be marked up for sentiment.

Angoss provides its technology through the cloud or on-site implementation. High levels of end-user functionality are claimed with much of the functionality available to business users. More advanced analysis can be achieved by combining text with structured data and text can be used to generate additional features for data mining activities.

Obviously this is a sophisticated product best suited to the needs of large organizations in the main, although the cloud based access will suit the needs of some mid-sized organizations too. Overall this is well suited to customer and marketing text analytics needs where text is used to gain insight into sentiment and customer behaviour.


Attensity

Attensity majors on social analytics, but also offers a general purpose text analytics engine. Four major components define the offering:

  • Attensity Pipeline collects data from over one hundred million social sources as input for analysis.

Clustify

Clustify, used mainly by legal firms, groups related documents into clusters, providing an overview of the document set and aiding with categorization. This is done without preconceptions about keywords or taxonomies — the software analyzes the text and identifies the structure that arises naturally. Clustify can cluster millions of documents on a desktop computer in less than an hour, bringing organization to large projects.

Clustify identifies important keywords used for clustering and reports frequency information so that clusters can be browsed which contain a set of specified keywords. It also identifies a representative document for each cluster, allowing decisions to be made on other documents in the same cluster.

Uses of Clustify include taxonomy development, search engine enhancement, litigation and ad targeting. The technology is built on proprietary mathematical models which measure the similarity of documents.

FICO

FICO provides sophisticated text analytics capability in its analytics tools and in the form of specific business solutions. At the heart of the offering is its Data Management Integration Platform (DMIP) addressing the complex issues associated with accessing diverse data sources and supporting a variety of analytics tools. Linguistic analysis supports tagging, dependency analysis, named entity extraction and intention analysis. Model Builder supports most forms of text analysis with parsing, indexing, stop words, n-grams, stemming, ‘bag of words’ analysis and so on. Some particularly sophisticated text analytics solutions are offered for fraud detection, employing Latent Dirichlet Allocation as a method of categorizing customers. In its traditional banking, insurance and financial services markets FICO utilizes text analytics to provide additional features in its scorecard technology.

A cloud based solution text analytics solution will soon be available. While Model Builder is a large sophisticated product, the cloud based offering will provide a much easier user interface when it is launched later in the year.


Fluent Editor

Fluent Editor 2014 from Cognitum is a comprehensive tool for editing and manipulating complex ontologies that uses Controlled Natural Language. Fluent editor provides a more suitable alternative to XML-based OWL editors. It’s main feature is the usage of Controlled English as a knowledge modeling language. Supported via Predictive Editor, it prohibits one from entering any sentence that is grammatically or morphologically incorrect, and actively helps the user during sentence writing. Controlled English is a subset of English with restricted grammar and vocabulary in order to reduce the ambiguity and complexity of the language.


IBM

IBM provides text analytics support through two products. IBM Content Analytics is primarily an extension of enterprise search technologies that adds several useful visualizations to discover structure within text data. LangaugeWare on the other hand leverages natural language processing (NLP) to facilitate several types of text analysis.

A major component within IBM Content Analytics is IBM Content Analytics with Enterprise Search. This supports the visualization of trends, patterns within text and relationships. Facets feature highly in the analysis. These are categories which are derived from text analysis. For example documents on infectious diseases might be categorized by a ‘hepatitis’ facet. The facet-pair view shows how facets (categories) are related to each other, and a dashboard facility allows several analyses to be viewed simultaneously. A connections view displays relationships between various facet values and a sentiment view allows the sentiment behind facets to be displayed. Other components in IBM Content Analytics are targeted at specific applications including healthcare and fraud. Content Classification supports the organization of unstructured content.

LanguageWare uses NLP techniques at the document level. This includes entity and concept recognition, knowledge/information extraction and textual relationship discovery.

As always with IBM these capabilities are offered within the context of supporting infrastructure and services and will primarily be of interest to larger organizations. There is nothing particularly interesting here, and it is likely that less costly and more capable solutions will be available for many text analytics needs.

Lexalytics

Lexalytics is one of the forerunners in text analytics and its Salience text analytics engine is used in market research, social media monitoring, survey analysis/voice of customer, enterprise search and public policy applications. The functionality offered by Salinece includes sentiment analysis, named entity extraction, theme extraction, entity-level sentiment analysis, summarization and facet and attribute extraction. The Salience engine can be integrated into other business applications via a flexible set of APIs, and can be tuned for very specific tasks and high levels of performance.

Another essential component in the Lexalytics approach is data directories. This effectively provides a parameter driven environment with files to set up relationship patterns, sentiment analysis, and the creation of themes. Non-English support is provided through this mechanism. Each directory can be configured to support a particular task delivering considerable flexibility and power.


Leximancer

Leximancer uses ‘concepts’ as a primary analytic structure, and these are automatically identified by the software without need for existing structures such as taxonomies or ontologies. Analysis is presented through a variety of useful visualizations, with drilling down to individual documents. It is used in survey analysis, market research, social media monitoring, customer loyalty and forensic analysis.

Leximancer Enterprise runs on a multi-user server providing users with a browser interface, and also provides a REST web services interface for application integration. A desktop version is available as a stand-alone environment, or users can access the LexiPortal via a web browser for a web based service (charging based on usage). Moderately priced academic versions are also available.


Linguamatics

Linguamatics provides a NLP capability with either in-house or cloud based implementation. A search engine approach to mining text comes with a good query interface and the ability to drill down to individual documents. A domain knowledge plug-in supports taxonomies, thesauri and ontologies.

The technology is widely used in life sciences and healthcare and the on-line service provides access to content in this domain. A web services API supports most programming languages.


Linguasys 

Linguasys primarily satisfies the need to process text in multiple languages – and by multiple we mean English, Arabic, Chinese, German, French, Hebrew, Indonesian, Japanese, Korean, Malay, Spanish, Pashto, Persian, Portuguese, Russian, Thai, Vietnamese, Urdu and others under development. This may well be unique in the world of natural language processing, and is possible because all languages are transformed into a large collection of concepts, each with its own identifier. It is the concepts which link all the languages together. The concept ‘mobile phone’ for example has the same concept number in all languages and is given identifier 26300, along with all variants that mean the same thing – ‘cellular phone’ for example.


Luminoso

Luminoso is a cloud based text analytics service that calls upon a multi-lingual capability. Many of the current problems associated with text analytics (ambiguity for example) are at least partly solved by Luminoso. A variety of useful reports and visualizations provide users with a particularly good interface.


MeaningCloud comes with as an Excel add-in and cloud based service. It provides feature level sentiment analysis, supports multiple languages, is easily integrated into other applications and automatically codes and classifies documents of any kind. It comes with a generous free plan, otherwise fees are based on usage.
