These systems and methods access a first knowledge graph associated with the context term to determine a potential term that is the meaning of the unknown term. Upon determining that there are multiple potential terms in the first knowledge graph that could be the meaning of the unknown term, the systems and methods take into account the temporal dimension of relationships between entities for disambiguating the meaning of the unknown term. The systems and methods achieve this by determining a time stamp of the text segment and accessing a second knowledge graph associated with the first context term and related to the time stamp to determine the potential term that is the meaning of the first unknown term. ## Claims ### Claim 1 A method for selecting meanings for terms susceptible to multiple meanings in a text segment displayed in an interactive media guidance application, the method comprising: receiving, through the media guidance application, a query comprising the text segment; identifying first unknown text in the text segment; analyzing the text segment for first context text; determining a meaning of the first unknown text by accessing a first knowledge graph associated with the first context text to identify a potential entity that is the meaning of the first unknown text, wherein the first knowledge graph defines a first set of entities and associations between the first set of entities; in response to determining that the first knowledge graph includes more than one potential entity that could be the meaning of the first unknown text: determining a time stamp associated with the text segment;

associating the first unknown text with the potential entity that is the meaning of the first unknown text; determining a result of the query based on the meaning of the first unknown text; and transmitting the result for display in the media guidance application. ### Claim 2 (depends on 1) The method of claim 1, wherein the second knowledge graph is associated with a specific time interval, and wherein a position of the specific time interval is determined based on the time stamp of the text segment. ### Claim 3 (depends on 2) The method of claim 2, wherein a duration of the specific time interval associated with the second knowledge graph is shorter than a duration of a time interval associated with the first knowledge graph. ### Claim 4 (depends on 2) The method of claim 2, wherein the position of the specific time interval associated with the second knowledge graph is such that the specific time interval associated with the second knowledge graph overlaps with the time stamp. ### Claim 5 (depends on 2) The method of claim 2, wherein the position of the specific time interval associated with the second knowledge graph is one of: a specific time interval associated with the second knowledge graph that precedes the time stamp of the text segment;
