Abstract text

The abstract text does not contain the word abstract or any author names. 

Keywords A list of keywords is not included in a conference abstract (as it is in a journal article abstract), but it is wise to use keywords in the abstract text and title. The inclusion of keywords facilitates electronic searches, making the work more accessible to others interested in your held. 

In most publications a clear distinction is made between sorption (interaction between sorbate and pre-formed particles of the adsorbent) and coprecipitation (particles are formed in the presence of foreign species). Sometimes, however, these two phenomena are confused, e.g. in [9, 10] the terms adsorption and sorption , respectively, are used in the title of the paper, abstract, text and figure captions, although the description of the experimental procedure clearly indicates that in fact coprecipitation was studied. Studies reporting only coprecipitation were not taken into account in the literature survey. 

Fig. 5. RLIMS-P text-mining results show summary of protein kinase, protein substrate, and phosphorylation position information extracted from a Medline abstract. Details of information extracted and words tagged as phosphorylation objects in the abstracts text are shown below the summary.

The standard bibliographic fields of accession number, author, title, date issued or publication date, and abstract text are present. Special fields include the home department number, which is assigned to the document by the issuing source, project codes, period covered (time during which the work was done), site at which the work was performed, and the security classification for the document. Date fields were designed to accommodate a four-digit year. 

The abstract text for each document averages about 150 words and is more indicative than informative of document content. However, when convenient, results and data are included. Words in the abstract and title are part of the Basic Index and are searchable using free text searching techniques. Because each sentence in the abstract is a unit, proximity searching can be used for more specific retrieval during free text searching. 

A recent survey showed that users were enthusiastic about this new database. Cross reference to CAS Registry Numbers and the capability to search polymers by class and monomer component were perceived as advantages. Comprehensive retrieval at specific and generic levels with controlled terms as well as free text searching of the abstract text and bibliographic data afforded good flexibihty. One command language to search both Du Pont proprietary and STN files was heartily welcomed. 

Abstract. Text entry research has received a lot of attention in recent years because of the need for more effective and usable entry methods on mobile devices. Technical limitations such as screen size have led to the design of entry interfaces that mentally load the user in order to obtain better performances. Current evaluation methodologies of these interfaces focus on text entry speed and error rate but don t pay enough attention to tbe mental load. In this paper, we concentrate on the evaluation of the load s effect on text entry process and we present a comparative evaluation of three mobile text entry methods with and without the application of a secondary task. We also define a performance measure that takes into account the mental load characteristic for a given text entry interface. 

Each publication containing new information of importance to chemistry or chemical engineering is abstracted in Chemical Abstracts. The individual abstracts are divided into two parts the first part comprises all the important bibliographic particulars, the second the abstract text. The latter is organized as follows the first sentence summarizes the new research results reported in the publication. The rest of the abstract highlights the following information ... 

All these indexes, but particularly the Keyword Index, differ from the half-yearly volume indexes. The entries in the issue indexes are extracted fi om the abstract text, not from the original literature. Thus, these indexes do not provide such in-depth and systematic coverage as the volume indexes. 

For using the Twelfth Collective Index on CD-ROM more effectively, the CA abstracts of the Twelfth Collective Period are offered on CD-ROM as well. Having selected CA abstract numbers from the CD-ROM disc the corresponding abstracts can be easily found. The abstract text on the CD-ROM is not searchable - in contrast to the online abstracts, that means it is not possible to search for terms in the abstract itself. 

The advantage of an online search for such a complex topic is demonstrated as an example in Fig. 122 (Sect. 7.3.2.4) and Sect. 9, which shows that Fischer-Tropsch is searchable in the CA file the searcher finds documents with Fischer-Tropsch as part of the text modifications or the abstract texts. But in addition all terms of the just developed search profile should be used to retrieve all relevant documents to this topic. Though the process of selecting relevant search terms is the first essential step for the online search, too. 

The abstract texts in Chemical Abstracts are not intended as substitutes for the contents of the original document. They should, however, furnish the reader with enough information to enable him to decide whether intensive study of the original document is worthwhile and if the costs for ordering or even translation are rewarding. There are many ways to obtain the original literature which is held at the disposal of central libraries in many countries for loan or for photocopying. Printed files and online databases make it possible for the user to identify the respective library.
