Methods, computer program, computer program product and indexing systems for indexing or updating index

An indexing system, comprising:

• a computer system;
• and
• a data storage system, said data storage system containing computer readable instructions executable by said computer system whereby said indexing system is operative to:
• detect a first feature within a first video frame of a video or within a first audio component of the video;
• identify a first keyword associated with the identified first feature;
• define a first time range for the first keyword based on a time stamp identifying the first video frame or the first audio component;
• detect a second feature within a second video frame of the video or within a second audio component of the video;
• identify a second keyword associated with the identified second feature;
• define a second time range for the second keyword based on a time stamp identifying the second video frame or the second audio component;
• determine that the second keyword overlaps with the first keyword, wherein the determining comprises determining that there is an overlap between the first time range and the second time range;
• and
• add to an index information indicating that the second keyword overlaps with the first keyword.

A computer program product comprising a non-transitory computer readable medium storing a computer program for indexing content, the computer program comprising computer readable instructions which when run on a computer system causes the computer system to:

• detect a first feature within a first video frame of a video or within a first audio component of the video;
• identify a first keyword associated with the identified first feature;
• define a first time range for the first keyword based on a time stamp identifying the first video frame or the first audio component;
• detect a second feature within a second video frame of the video or within a second audio component of the video;
• identify a second keyword associated with the identified second feature;
• define a second time range for the second keyword based on a time stamp identifying the second video frame or the second audio component;
• determine that the second keyword overlaps with the first keyword, wherein the determining comprises determining that there is an overlap between the first time range and the second time range;
• and
• add to an index information indicating that the second keyword overlaps with the first keyword.

An indexing system for indexing or updating an index for content, comprising:

• a data storage system;
• and
• a data processor coupled to the data storage system, the data processor being configured to:
• detect a first feature within a first video frame of a video or within a first audio component of the video;
• identify a first keyword associated with the identified first feature;
• define a first time range for the first keyword based on a time stamp identifying the first video frame or the first audio component;
• detect a second feature within a second video frame of the video or within a second audio component of the video;
• identify a second keyword associated with the identified second feature;
• define a second time range for the second keyword based on a time stamp identifying the second video frame or the second audio component;
• determine that the second keyword overlaps with the first keyword, wherein the determining comprises determining that there is an overlap between the first time range and the second time range;
• and
• add to an index information indicating that the second keyword overlaps with the first keyword.

A content indexing method performed by an indexing and search system, the method comprising:

• automatically detecting a first feature within a first video frame of a video or within a first audio component of the video;
• identifying a first keyword associated with the identified first feature;
• automatically detecting a second feature within a second video frame of the video or within a second audio component of the video;
• identifying a second keyword associated with the identified second feature;
• storing in a data storage system the first and second keywords;
• defining a time range for the first keyword;
• after defining the time range for the first keyword, determining that the second keyword falls within the defined time range;
• and
• in response to determining that the second keyword falls within the defined time range, updating a first set of keywords by adding the second keyword to the first set of keywords, wherein the first set of keywords is associated with the first keyword.
