About Textpresso Categories/Ontology Copyright Downloads Feedback Home Query Language Search User Guide
Enter keyword(s) and/or category/ies. Selecting categories for a query makes a search more specific. For example, you can retrieve sentences that contain the word HSN and a Oryza sativa gene name by typing the keyword 'SPW1' and choosing the category 'gene (Oryza sativa)'. A category hit occurs when a particular word or phrase in the sentence is defined as a member of a particular category. Categories will be concatenated by a Boolean 'and' operation to other categories and keyword(s) if present. To search for terms in categories, click on the Categories/Ontology link above.
Keywords
Separate multiple, required keywords by white spaces (Boolean 'and').
Separate multiple, alternative keywords by a comma with no white spaces (Boolean 'or').
Enter phrases in double quotes, and put a '-' sign in front of words which are to be excluded.

[ Sen. 1, subscore: 4.00 ]: BACKGROUND : Plotless density estimators are those that are based on distance measures rather than counts per unit area ( quadrats or plots ) to estimate the density of some usually stationary event , eg burrow openings , damage to plant stems , etc These estimators typically use distance measures between events and from random points to events to derive an estimate of density .

[ Sen. 11, subscore: 2.00 ]: CONCLUSION : Plotless density estimators can provide an estimate of density in situations where it would not be practical to layout a plot or quadrat and can in many cases reduce the workload in the field .
