How SAS® Is Different
- SAS offers flexible options to suit your organization's needs as you get started with content categorization efforts. Add-ons for industry-specific taxonomy starter kits contain prebuilt rules that define concepts and their attribute values and provide detailed taxonomies. Wikipedia and DBPedia are integrated with SAS Enterprise Content Categorization – you can use no-cost downloads to automatically generate categories and subcategories and to extract entities.
- Get the most from your investment using prebuilt, in-depth methods to understand content and to ensure that you can apply the technology to different corpora. Easily create advanced linguistic rules with prebuilt rule-development operators such as co-referencing, triple detection, stemming functions, and case-insensitive operators as well as predefined extraction concepts and automated rule generation.
- Extend your unstructured content knowledge with SAS Enterprise Content Categorization and turn masses of content and document collections into reusable assets that span departmental silos, regardless of owner or location. For example, test documents that are stored in Microsoft Excel or use the conversion tools to standardize different document formats.
- The solution is part of the SAS Business Analytics Framework, so you can integrate text insights into other fact-based information systems. Use machine-generated Boolean rules discovered in SAS Text Miner as inputs to your categorization projects, and bring your ontologies defined in SAS Ontology Management to the categorization server to classify your content with semantic terms. The result is faster, more efficient information insight and better relevance, to boost knowledge retention and sharing. Use the taxonomies from your categorization projects in SAS Sentiment Analysis to derive detailed opinions from the taxonomy concepts.
- Find the information you need, when you need it. Find the information you need regardless of whether it's been used before or whether you know its exact location. The flexible, intuitive software provides multiple ways to improve content retrieval, as it accurately defines metadata from the content itself and delivers only the most meaningful material related to your needs.
- Improve efficiency and purge content chaos. In the era of inexpensive commodity storage, it isn't efficient or effective for organizations to retain all of their data. By categorizing and extracting texts based on sophisticated linguistic rules and taxonomies, you keep only what is needed – and you can filter the information even before it has been stored, to reduce overhead.
- Extend existing investments. The software transforms corporate textual data into a reusable asset, extending the value of predefined investments by building upon existing indexes and integrating with content management systems like Documentum and Microsoft SharePoint, and with search technologies like Endeca and FAST ESP.
- Identify interrelationships between categories and concepts and adjust relevance schemes for concepts, as well as for priorities of concepts and their associated rules.
- Automatically generate rules using features such as frequent phrase extraction and maximum entropy classifiers.
- Refine models, using straightforward graphical reports that illustrate relevant statistics for category matches and show the precision, recall and numbers of passing and failing documents.
- Specify XPath expressions in Boolean category rules to locate matching content in XML elements.
- Jump-start taxonomy development efforts using no-cost downloads to automatically generate categories and subcategories from Wikipedia in different languages.
- Use syntax checking and duplicate rule elimination for classifier concepts.
- Automatically apply NLP/advanced linguistic technologies to classify and identify key information.
- Use linguistic rules (unique, identifying terms) – and/or add Boolean operators to your unique terms – for added specificity in determining category membership.
- Author simple or complex category rules and concept definitions.
- Develop a list of unique identifying terms for each category rule.
- Weight selective terms or the categories themselves to create more exclusive membership requirements.
- Use test and document interfaces to validate the application of rules and definitions to batch, entire or content components.
- Automatically apply rules and definitions to incoming texts using the client APIs in C#.NET, Java, Perl or Python.
- Entity and fact extraction
- Use predefined extraction concepts to shorten the rule-writing process, including: address, location, date, phone number, SSN, person, time and more. New keyboard shortcuts simplify rule writing.
- Extract entities from DBPedia with predefined plug-ins, available as no-cost downloads.
- Detect triples, such as subject-verb-object relationships.
- Hyperlink concept matches for extractions.
- Use prebuilt co-reference operators and enhanced pronoun resolution rules in an intuitive GUI to help resolve pronouns more easily, addressing syntactical functions such as:
- Linking to a matched string with its canonical form.
- Co-referencing classifier definitions.
- Restricting forward and preceding co-reference matches.
- Use UNLESS and NOT operators to limit matches.
- Limit XML fields for specified matches.
- Use case-insensitive operators for greater rule-matching precision, including:
- Prebuilt stemming to match on all word forms or only on noun or verb forms.
- Paragraph operator to define the number of word, noun or verb matches within a paragraph.
- Sentence operators to consider the maximum number of sentences and the number of beginning or ending words within a sentence where a match can occur.
- Locate and return related pieces of data that form a fact or an event based on their context in real time (e.g., a person in relation to a company, the merger of two companies, etc.).
- Identify unknown information and write context-specific rules that automatically extract facts and events without a requirement for precompiled dictionaries.
- Automatically return only the facts and events with the highest priority or those with the longest match.
- Customize matching criteria using these options:
- Contextual markers.
- Parts of speech.
- Identifiers for lower- or uppercase words.
- Boolean operators.
- Write more than one rule to extract all of the possible permutations of the data you're seeking.
- Disambiguate facts and events by excluding certain matches.
- Distill vast quantities of information into simple concepts and a few easy-to-understand pieces of information.
- Use dictionary, grammar and regular expression-based concepts to simplify the process of locating related data that's needed for subject-matter expertise.
- Perform complex information tasks using an intuitive GUI.
- Automate the customized classification and entity application to large volumes of multilingual content that's acquired, generated or may exist in a repository.
