annotation

Bioinformatics A term of art referring to analysis and commentary added to sequence data in databases, which provide contextual information about coding and non-coding sequence within genes, patterning and motifs, similarities, known or predicted protein structure and function, and links to external data (e.g., clinical observations).
Informatics A critical or explanatory note, usually included in a bibliographical entry or reference, to provide additional data.

annotation

process used in GENOMICS for analysis of NUCLEOTIDE SEQUENCES to identify the GENES (both PROTEIN-coding and protein non-coding, such as those for rRNA and tRNA), their regulatory sequences (see OPERON MODEL and their functions. Annotation also includes characterization of MOBILE GENETIC ELEMENTS and REPETITIVE DNA. See also BIOINFORMATICS.

2) Both-freeze: This condition pauses the local user's view together with the remote user's view while the remote user uses the freeze interface to draw annotations. This is based on participants' suggestion from the first study, and similar to Fakaurfar's auto-freeze interface [34] except in the use of annotation stabilization and the local user device type.
In this paper, we described two user studies on user interfaces for better remote collaboration with visual annotation cues.
As shown in Figure 1, in the first loop, the number of neighbor proteins with GO annotations (D and E) interacting with unidentified protein A is 2, the GO annotation of protein D is 2, 3, 4 and the GO annotation of protein E is 1, 2, 6, and 7, only the annotation 2 in all the functional annotations of the neighbor proteins satisfies the condition of m/n [greater than or equal to] 75%, then annotation 2 was annotated to protein A.
Partners also have API access to annotation data across their content, which they can then use to display annotations elsewhere on their website for promotional purposes or further analyse through text and data mining.
The visible annotation developed in this study intends to provide a learning strategy that considers the collaborative knowledge-building process and includes the linked-annotation function to enhance the accuracy of shared knowledge and foster higher-quality knowledge construction for online discussion.
To be generally useful to many organizations in the research community, the data annotations have to be consistent, generally agreed on, and well documented.
Automatic image annotation and image retrieval application can bring the convenience to the users, and also provide a simple and easy way for users to view and manage their photos.
Section 4 will describe in detail the different mechanisms we propose to support collaborative semantic annotation of shared resources: a Tag Recommender (representing a novel contribution of this paper) and a Personal View Manager (whose implementation is described in a previous work [6]); Section 5 will present the user evaluation of the prototype implementing the proposed functionalities and represents the major contribution of this paper.
In the past several decades, the main concentration of the researches on semantic annotation is semantic annotation tools and platforms, semantic annotation of Web documents, and semantic annotation in IoT.
Despite these efforts, most of existing annotation methods combine the information from different image features by concatenating them into a long feature vector, which treats all the features equally and omits their different contributions for the final decision.
Due to experimental techniques and the research bias in biology [3, 4], the gap between newly discovered genome sequences and functional annotations of these sequences is becoming larger and larger.
"The question is a close one and important considerations of public policy are at stake on either side but, at the end of the day, we conclude that the annotations in the OCGA [Official Code of Georgia Annotated] are sufficiently law-like so as to be properly regarded as a sovereign work," U.S.
