What is another method of indexing

Index term explanation and definition

Indexing refers to the method, which has been used for centuries, of indexing entire books or longer to long texts. The page number specific keyword list of the index is designed for readers who are looking for an overview in an extensive text, optionally structured according to chapters, for specific terms, names or facts. Indexing and indexing are to be regarded as equivalent.

The index, created in the appendix or appendix of a written work, must be structured as a catalog and formatted. Important, meaningful single words, word combinations, terminology, people and institutions are referenced in the index and read out with page numbers (position references in the text).

Alphabetical sorting

Using the alphabetical order of the index, the reader can quickly find out about the occurrence of specific ones Catchwords in the text and can look up selected text passages using the page numbers.

Page numbers in the index

Each element that receives an index entry must be noted with a referential page number. In the case of consecutive page numbers, only the first has to be named and I should be followed by an f. For "follows". To be read informatively as: Das indexed element can be found on the referenced page and on the next.

If the referential page number of an element is marked with two "ff." For the following, it means that the element is specified on the referential page and on several subsequent pages.

The informal intention of indexing

Indexing thus fulfills an informal intention. Elements, individual terms, names, facts that are expected to be of particular interest to readers can be optically filtered out and looked up more quickly. On the one hand, the use of Overview information of the index is the reading time. Because interesting, informative text passages can be found and noted more quickly. On the other hand, successive reading is not the only method of accelerated text indexing.

DIN standard for indexing

In general, it is advisable to index any extensive document in order to speed up the targeted search for content. Indexing (guidelines and practice) are a self-sufficient subject area of Information science. The indexing of documents is regulated by DIN standard 31623.

Indexing rules

Indexing rules specify how index terms are to be optimally formulated so that contextual content can also be found in print and in the WWW or from search engines be represented.

Free indexing

The indexer is not bound by a concept as to which content is transferred from the text to be indexed to the index. The Indexer practically makes a subjective selection as to which descriptors are represented in the index.

Controlled indexing

With controlled indexing, the indexer is bound by technical requirements. The terminological requirements of the thesaurus for the subject area from which the text to be indexed originates must be observed when compiling the index.

Function of the thesaurus

Every science or subject area has a continuously updated thesaurus of applied technical terms. Technical terminology, which is compiled in the disciplinary thesaurus represent the basic vocabulary of a controlled index. Attached to a text that deals thematically with its subject.

Indexing and documentation language

Optimal indexing is supported if the document is written in a formally standardized documentation language. Unified in the documentation language Documents are considered to be easier to index, among other things because the documentation / technical language can conventionally be assumed to be known. Descriptive descriptors can be found, indexed, and cross-referenced more efficiently. An indexer who is familiar with the subject indexes terminology-bound facts more competently and efficiently and uses them to form qualified index terms.

Indexing methods

Of the three methods, language-based indexing using descriptors is the most common. The other two methods are indexing by assigning labels in an artificial (character) language or as e.g. B. Classifying notation.
Intellectual indexing
The most common method of indexing is language-based using descriptors. If the indexer works with the document, compiles descriptors, it is an intellectual indexing.
Descriptors or descriptors are content (individual words, terms, names or numbers) documented in the text, which the indexer assesses as relevant and selectively recorded. Descriptors are differentiated into keywords and key words:

  • Keywords are used in the text / document to be indexed. The indexer uses keywords from the text to create an index.
  • Keywords are not part of the text. The indexer creates an associative connection between text content and the specific keyword.

Automatic indexing
Automatic indexing is a digital process without human intervention.
Computerized indexing
Computerized indexing can be as efficient as intellectual indexing. The indexer creates an index of the edited document file using a Layout software with index function. For this purpose, appropriate words, terms, phrases must be specially marked (linked) in the document. The index is generated automatically according to the identification of the indexer. A computer-aided generated index has to be designed in accordance with the document and can be versioned as required.

From meta tags to search terms on the Internet

The technology of indexing is expanding to include websites in the digital Internet world. Indexing websites works differently. No index is created. Website indexers have greater freedom in assigning keywords and key words. Web-compliant indexing, more of a keywording, is entered directly in the MetatagArea of ​​the HTML codes incorporated into the website.

Online or Internet research is a technique and method to find suitable web references with search term compliant content from the reservoir of indexed website content (content) in search engines.

Index terms, as identifiers (descriptors) for contents of a structurally self-contained text, are automatically acting in the World Wide Web Search robots frequented.

The meta tag: Keyword

The exclusive possibility to increase the search engine representation of the designed website on the World Wide Web is the description of the content with keywords, separated by commas, in the meta tag area. Descriptive keywords and keywords are entered in the HTML code of websites in the meta tag or header area. The functional meta tag is "keyword". Search robots apperceive content, that is, keyword and keyword chains of the meta tag "keyword" and report their results cyclically to the index generator of Search engine back.

Problematic indexing and "Dublin Core"

Search engine indexing using metatag content, which practically specifies individual websites, shows disadvantages in that metatags keywords are not infrequently manipulated to make them individual Search engine ranking to increase.

Dublin Core“Is the name of an initiative on the Internet to create a system of website descriptors through structured meta tags.

Indexing on the Internet

In the Internet, web pages must be indexed if they can be researched by topic in search engine keyword indexes, such as Google, Bing or Yahoo should be listed. Indexing websites is equivalent to free indexing. It could also be described as associative indexing.

Index rules

Index rules specify which text content is relevant and how the indexer proceeds in order to selectively recognize meaningful words, terms and phrases and to include them in them.

The index position is always a matter of selectively recognizing words, terms and phrases and compiling them with reference to them so that they summarize and reproduce the text content on a topic-specific basis. When it comes to indexing web pages, it's basically about nothing else: the lexigraphic description of the specific text content in the meta tag of the HTML web document.

Get it on the web Index terms two functions:

  1. As an index term you describe Website content.
  2. Suspected index terms are used in Internet research (Online research via search engine) are used as thematically meaningful search terms.

The online research uses a search engine to search for individual or combined search term connections and focuses on website search results that have specified search terms in the meta tag area. What is used as a search term in online research is the meta tag in web design.

In order for the search term to also call up the appropriate website via the online search, meta tags must generally be formulated in accordance with the search term. The requirement for the indexing web designer is clearly:

How can the website content in the meta tag area be optimally described with an enumeration of meta tags so that online research via adequate search engine input leads to the website?

Index terms and search terms can differ in length and number, but should never longer than 200 characters be. In the metatag area of ​​websites, the number of descriptive keywords should be limited to a few.
