Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

 Appl.No 1260136 Applicant RENAULT SAS Inventor ZINOUNE CLEMENT
The method involves identifying a roundabout (20), and locating the identified roundabout (30). Parameters characterizing the roundabout are recorded (40) in a digital navigation map, where the roundabout is identified by estimating the trajectory of a vehicle over a predetermined distance traversed by the vehicle. The trajectory is estimated from different successive states of the vehicle, where each state is estimated using data selected from yaw speed, speed, difference in speed of the rear wheels of the vehicle, and a gearbox ratio.

 Appl.No 1050881 Applicant RENAULT SA Inventor LE-MARCHAND OLIVIER
The method involves obtaining Doppler measurements from satellite signals by obtaining measurements of pseudo-distances from the satellite signals, where the measurements are carried out by sensors (5) e.g. gyroscope. An error is detected by testing the existence of a Doppler measurement error and identifying a satellite with the emitted signals at the origin of the error in the event of existence of the measurement error to test the existence of the measuring error. The obtained measurements are removed using a signal emitted by a satellite i.e. global positioning system (GPS) satellite. Independent claims are also included for the following: (1) a data recording medium comprising a set of instructions for estimating a positioning state of a motor vehicle (2) a device for determining a state of a motor vehicle comprising hardware and/or software units.

The invention concerns a method for selecting a restricted or empty set of hypotheses (Z1 - Z8) of possible positions of a vehicle from a plurality of hypotheses. The invention involves: - a step of acquiring at least one geolocated position (P0) of the vehicle by means of a geolocation system, - a step of acquiring a plurality of hypotheses of possible positions of the vehicle, - a step of determining the covariance of the geolocated position of the vehicle and the covariance of each acquired hypothesis, - a step of calculating, for each acquired hypothesis, a Mahalanobis distance, and - a step of selecting a restricted or empty set of hypotheses from the acquired hypotheses.
