Abstract: The disclosure related to the field of language processing. A server (30) is configured to respond to a query associated with a user device (21) by sending, to the user device (21), an indication of an item selected based on semantic importance attributed to grams of text in the query. Attributing semantic importance comprises: in the event that a number of occurrences of the gram in a first document is above an occurrence threshold, determining a gram score for said gram based on said number of occurrences; in the vent that the number of occurrences of the gram in the first document is below the occurrence threshold, determining the gram score based on: (i) said number of occurrences, and (ii) a reference score for the gram based on a number of occurrences of the gram in a reference document different to the at least one first document; and attributing the semantic importance based on the gram score.

Abstract: Disclosed herein is a method and apparatus including a server (100) comprising: (i) a data store (110) comprising a plurality of stored metrics, each associated with a corresponding one of a plurality of facilities; and a processor (120) coupled to the data store (110). The server (100) is configured to receive a metric message comprising metric data associated with an identified one of the plurality of facilities. The processor (120) is configured to provide an update of the stored metric for the identified facility based on the stored metric and the metric data, such that more recent metric data contributes more to the updated metric than less recent metric data. The server 100 is configured to respond to a request message from a User Equipment (“UE”) 301,302,303 by sending, to the UE 301,302,303, a facility message indicating a degree of prioritisation for the facilities based on the updated metrics.

Abstract: Described herein is a system and method of controlling an optical heterodyne measurement system (1). The measurement system (1) has a tunable laser (9) for generating a local oscillator signal, an optical input (5) for receiving an input optical signal (7) and a mixing module (13) for mixing the local oscillator signal with the input optical signal to generate an output optical measurement signal. One embodiment provides a method including the steps of: a) receiving an input electrical drive signal for driving the tunable laser (9) to produce a laser output having a spectral linewidth and peak central frequency; b) coupling the input electrical drive signal with an electrical linewidth control signal (54) to selectively broaden the spectral linewidth; and c) during a measurement period, selectively tuning the central frequency of the laser in a stepwise manner across a predetermined frequency spectrum at predefined tuning increments.

Abstract: Described herein is an optical channel monitor (1) including a protective housing (3), an input port (5) disposed in the housing (3) and configured for receiving at least one input optical signal (7) including one or more optical channels separated by wavelength. A wavelength configurable laser (9) is located within the housing (3) and is configured to provide an optical reference signal (11) at a first wavelength (?r). The laser (9) is adapted to scan across a range of wavelengths covering the one or more optical channels. An optical mixing module (13) is coupled to the input port (5) and the laser (9) for mixing the input optical signal (7) with the optical reference signal (11) to produce a mixed output signal. A receiver module (15) is configured to receive the mixed output signal and extract signal information indicative of at least the optical power of the at least one input optical signal at the first wavelength (?r).
