Content Enhancement & Knowledge Services

Keyword/ Semantic Indexing

Description of Services

Indexing is a process where the key descriptors that can represent the core theme of an article or a document are extracted and such article or document is tagged with those descriptors. Such descriptors can be in the form of keywords that are actually present in the document (keyword indexing) or descriptors that represent the key concepts elaborated in the article, but not necessarily to be present in the document (Semantic Indexing).

Specific Scope Offerings

The range of Scope's Indexing Services include:

Keyword Indexing
Scope provides keyword based indexing services to index patents, non-patent technical literature, news articles, E-learning content and product data. We use standard domain specific thesauri and taxonomies to index technical documents.

Our English language indexing services can also be extended to STM literature generated in other major languages like French, German, Chinese, Japanese, Korean etc., through a process of translation and indexing.

Conceptual/ Semantic Indexing
Scholarly literature and patents require a high level of conceptual understanding. Indexing these documents based on the keywords present in the articles may not provide the precision and conceptual accuracy demanded by discerning researchers.

Scope's semantic indexing methodology identifies the key concepts that are specific to the type of document - e.g., novelty in patent and technical parameters in a non-patent technical literature. Our indexers identify those portions of the documents which represent these concepts and use standard descriptors using domain-specific controlled vocabularies to index those documents.

Journal Indexing
Scope offers journal indexing services to leading A&I services and online aggregators of journals. We capture all the metadata related to a journal and provide the keywords that represent the core concepts or themes of the journal issues.

Subject Category Indexing
Scope offers very deep, granular subject categorization for all scholarly output published in the form of articles, dissertations, conference proceedings, grey literature etc. We can also provide indexing services based on standard library classification like Dewey, LoC (Library of Congress Classifications), colon classification and other domain specific categorizations.

Image Indexing
Indexing of non-textual objects like medical images, tables, graphs, photographs, topographical maps, multimedia products like podcast, videocast, animation etc. is also possible. At Scope, we use our rich resources of Subject Matter Experts in Healthcare and other Life Sciences to index radiological images, chemical structures and gene sequences. Our indexing of these objects, not only captures the basic metadata embedded in the images, but also provides semantic annotations based on the concepts that are represented by these images.

Domain Specific Niche Indexing Services

Scope also offers domain specific niche indexing services, which require deep knowledge and expertise in the particular domain. Some of the services in this area are:

Medical Indexing and Coding/ Evidence Based Rating
The medical experts at Scope are well versed in all the standard nomenclatures used in medical coding and indexing like ICD9 and 10, CPT, SNOMED, CPT, etc. We can also provide customized coding and indexing services based on the client specified coding nomenclatures that are used for the specific subspecialties - for e.g., IPCCC codes used for Congenital Heart Disease and other such specialty specific codes.

Scope's medical experts can also provide the ratings for clinical evidence by analyzing the various clinical trials literature such as meta-analysis, systematic reviews, randomized controlled trials, case reports, etc.

Drug Indexing
We provide our niche indexing services to pharmaceutical companies by indexing all pertinent information of a drug that is used in clinical trials and medical cases and index drug characteristics such as therapeutic usage, pharmacokinetics, and pharmacovigilance, patient demographics, etc.

Chemical Structure Drawing and Indexing
Scope can provide indexing of the structures of existing chemical compounds and draw structures for new compounds and substances that are described in patents and other non-patent technical literature. We have the expertise to draw structures based on IUPAC nomenclature, SMILE notations and InChI identifiers.

Scope Methodology

Scope uses a process of Machine Aided Human Indexing

The company uses the following methodology in their indexing process:

  • Fully automated tool for extraction of document level metadata e.g. title, author, image captions etc.
  • Use of assisted automation, where domain specific taxonomies and ontologies that are existing and used as de facto standards are used to automatically index documents for a general or broad domain and further validated by subject matter experts, e.g. Chemical, Medical, Pharmaceuticals, Life Science, Biotechnology, Engineering etc.
  • Fully manual indexing by human experts, for more complex and specialized domains within a particular subject area e.g. cardiovascular in medical, nanotechnology in Engineering, Genetics in Life Sciences, etc.

Client Benefits

Our indexing experts have considerable experience in indexing and tagging products according to standard nomenclature - which means, the users of your databases spend less time in finding information. This will also increase the usability and precision of your search and retrieval platform, the return on investment on your content management systems.
