00:08:16.999 --> 00:08:17.009 align:start position:0% problem the worst problem is that 00:08:17.009 --> 00:08:19.610 align:start position:0% problem the worst problem is that aggregation<00:08:17.520> functions<00:08:18.029> are<00:08:18.180> personal<00:08:18.779> it's 00:08:19.610 --> 00:08:19.620 align:start position:0% aggregation functions are personal it's 00:08:19.620 --> 00:08:22.070 align:start position:0% aggregation functions are personal it's like<00:08:19.830> if<00:08:20.729> somebody<00:08:21.240> says<00:08:21.539> this<00:08:21.719>

00:08:24.539 align:start position:0% movie and somebody else is if this is a 00:08:24.539 --> 00:08:26.749 align:start position:0% movie and somebody else is if this is a good<00:08:24.630>

a bad movie maybe I will 00:08:26.759 --> 00:08:29.029 align:start position:0% good movie or a bad movie maybe I will trust<00:08:27.090> him<00:08:27.330> more<00:08:27.539> because<00:08:28.110> or<00:08:28.590> I<00:08:28.650> will<00:08:29.009> use 00:08:29.029 --> 00:08:29.039 align:start position:0% trust him more because or I will use 00:08:29.039 --> 00:08:30.589 align:start position:0% trust him more because or I will use this<00:08:29.310> information<00:08:29.669> and<00:08:30.060> not<00:08:30.240> that<00:08:30.419> one 00:08:30.589 --> 00:08:30.599 align:start position:0% this information and not that one 00:08:30.599 --> 00:08:33.560 align:start position:0% this information and not that one because<00:08:31.259> i<00:08:31.529> know<00:08:32.039> i<00:08:32.190> have<00:08:32.370> some<00:08:32.820> kind<00:08:33.180> of<00:08:33.270> like 00:08:33.560 --> 00:08:33.570 align:start position:0% because i know i have some kind of like 00:08:33.570 --> 00:08:36.860 align:start position:0% because i know i have some kind of like good<00:08:34.409> with<00:08:34.649> him<00:08:34.860> or<00:08:35.039> is<00:08:35.820> my<00:08:36.029> friend<00:08:36.360> I<00:08:36.539> know<00:08:36.599> he 00:08:36.860 --> 00:08:36.870 align:start position:0% good with him or is my friend I know he 00:08:36.870 --> 00:08:39.399 align:start position:0% good with him or is my friend I know he likes<00:08:37.050> the<00:08:37.320> same<00:08:37.469> things<00:08:37.740> I<00:08:37.860> like<00:08:38.099> so<00:08:38.909> it's 00:08:39.399 --> 00:08:39.409 align:start position:0% likes the same things I like so it's 00:08:39.409 --> 00:08:42.290 align:start position:0% likes the same things I like so it's that<00:08:40.409> I<00:08:40.440> use<00:08:40.800> that<00:08:40.829> source<00:08:41.430> better<00:08:41.849> than<00:08:42.060> that 00:08:42.290 --> 00:08:42.300 align:start position:0% that I use that source better than that 00:08:42.300 --> 00:08:44.300 align:start position:0% that I use that source better than that other<00:08:42.510> source<00:08:42.959> source<00:08:43.229> we<00:08:43.680> have<00:08:43.829> some<00:08:44.010> kind<00:08:44.250> of 00:08:44.300 --> 00:08:44.310 align:start position:0% other source source we have some kind of 00:08:44.310 --> 00:08:49.010 align:start position:0% other source source we have some kind of weighted<00:08:44.910> by<00:08:45.510> source<00:08:46.040> function<00:08:47.040> right<00:08:47.550> so<00:08:48.510> my 00:08:49.010 --> 00:08:49.020 align:start position:0% weighted by source function right so my 00:08:49.020 --> 00:08:50.510 align:start position:0% weighted by source function right so my weights<00:08:49.320> are<00:08:49.560> very<00:08:49.829> different<00:08:50.040> than<00:08:50.279> your 00:08:50.510 --> 00:08:50.520 align:start position:0% weights are very different than your 00:08:50.520 --> 00:08:53.510 align:start position:0% weights are very different than your weights<00:08:50.760> so<00:08:51.360> it's<00:08:51.540> a<00:08:51.690> personal<00:08:52.320> function<00:08:52.740> so 00:08:53.510 --> 00:08:53.520 align:start position:0% weights so it's a personal function so 00:08:53.520 --> 00:08:55.639 align:start position:0% weights so it's a personal function so that's<00:08:54.000> a<00:08:54.120> general<00:08:54.540> function<00:08:54.779> makes<00:08:55.140> sense<00:08:55.500> at 00:08:55.639 --> 00:08:55.649 align:start position:0% that's a general function makes sense at 00:08:55.649 --> 00:08:57.620 align:start position:0% that's a general function makes sense at all<00:08:55.770> you<00:08:56.550> have<00:08:56.670> to<00:08:56.790> think<00:08:56.820> about<00:08:57.149> it<00:08:57.270> really 00:08:57.620 --> 00:08:57.630 align:start position:0% all you have to think about it really 00:08:57.630 --> 00:08:58.700 align:start position:0% all you have to think about it really well 00:08:58.700 --> 00:08:58.710 align:start position:0% well 00:08:58.710 --> 00:09:02.720 align:start position:0% well and<00:08:58.800> also<00:08:59.700> always<00:09:00.480> consider<00:09:01.410> or<00:09:01.680> make<00:09:02.460> it<00:09:02.610> very 00:09:02.720 --> 00:09:02.730 align:start position:0% and also always consider or make it very 00:09:02.730 --> 00:09:04.610 align:start position:0% and also always consider or make it very transparent<00:09:03.150> for<00:09:03.510> people<00:09:03.810> to<00:09:03.960> see<00:09:04.140> how<00:09:04.350> that 00:09:04.610 --> 00:09:04.620 align:start position:0% transparent for people to see how that 00:09:04.620 --> 00:09:06.350 align:start position:0% transparent for people to see how that function<00:09:04.980> is<00:09:05.040> calculated<00:09:05.610> because<00:09:05.880> then<00:09:06.240> you 00:09:06.350 --> 00:09:06.360 align:start position:0% function is calculated because then you 00:09:06.360 --> 00:09:09.050 align:start position:0% function is calculated because then you can<00:09:06.570> decide<00:09:06.720> if<00:09:07.280> thats<00:09:08.280> functions<00:09:08.640> applies<00:09:08.910> to 00:09:09.050 --> 00:09:09.060 align:start position:0% can decide if thats functions applies to 00:09:09.060 --> 00:09:12.860 align:start position:0% can decide if thats functions applies to you<00:09:09.210> or<00:09:09.300> not<00:09:09.420> i<00:09:11.270> have<00:09:12.270> done<00:09:12.450> this<00:09:12.570> little 00:09:12.860 --> 00:09:12.870 align:start position:0% you or not i have done this little 00:09:12.870 --> 00:09:15.980 align:start position:0% you or not i have done this little experiment<00:09:13.140>

amazon okay<00:09:18.960> I've<00:09:19.200> just<00:09:19.260> a<00:09:19.860> lot<00:09:19.980> of<00:09:20.420> presenting<00:09:21.420> wheel 00:09:21.560 --> 00:09:21.570 align:start position:0% okay I've just a lot of presenting wheel 00:09:21.570 --> 00:09:24.680 align:start position:0% okay I've just a lot of presenting wheel of<00:09:21.750> options<00:09:22.200> all<00:09:22.440> with<00:09:23.070> a<00:09:23.100> number<00:09:23.760> from<00:09:24.360> one<00:09:24.660> to 00:09:24.680 --> 00:09:24.690 align:start position:0% of options all with a number from one to 00:09:24.690 --> 00:09:27.920 align:start position:0% of options all with a number from one to five<00:09:25.140> or<00:09:25.410> 3.8<00:09:26.130> or<00:09:26.160> something<00:09:26.640> ok<00:09:27.360> I<00:09:27.570> see<00:09:27.780> this 00:09:27.920 --> 00:09:27.930 align:start position:0% five or 3.8 or something ok I see this 00:09:27.930 --> 00:09:30.290 align:start position:0% five or 3.8 or something ok I see this is<00:09:28.020> one<00:09:28.290> to<00:09:28.620> five<00:09:28.800> stars<00:09:29.100> and<00:09:29.400> then<00:09:29.970> I<00:09:30.060> see<00:09:30.210> okay 00:09:30.290 --> 00:09:30.300 align:start position:0% is one to five stars and then I see okay 00:09:30.300 --> 00:09:32.570 align:start position:0% is one to five stars and then I see okay the<00:09:31.170> system<00:09:31.500> has<00:09:31.530> three<00:09:31.920> point<00:09:32.130> eight<00:09:32.250> out<00:09:32.520> of 00:09:32.570 --> 00:09:32.580 align:start position:0% the system has three point eight out of 00:09:32.580 --> 00:09:35.840 align:start position:0% the system has three point eight out of 5<00:09:32.940> stars<00:09:33.270> but<00:09:34.170> well<00:09:34.680> amazon<00:09:35.280> figured<00:09:35.550> out<00:09:35.640> that 00:09:35.840 --> 00:09:35.850 align:start position:0% 5 stars but well amazon figured out that 00:09:35.850 --> 00:09:38.450 align:start position:0% 5 stars but well amazon figured out that doesn't<00:09:36.450> helps<00:09:36.780> too<00:09:37.020> much<00:09:37.170> people<00:09:37.620> so<00:09:38.400> you 00:09:38.450 --> 00:09:38.460 align:start position:0% doesn't helps too much people so you 00:09:38.460 --> 00:09:40.160 align:start position:0% doesn't helps too much people so you need<00:09:38.670> to<00:09:38.760> also<00:09:38.910> add<00:09:39.150> how<00:09:39.450> many<00:09:39.660> people<00:09:39.840> have 00:09:40.160 --> 00:09:40.170 align:start position:0% need to also add how many people have 00:09:40.170 --> 00:09:42.260 align:start position:0% need to also add how many people have raid<00:09:40.620> that<00:09:40.860> thing<00:09:41.160> because<00:09:41.970> it's<00:09:42.120> different 00:09:42.260 --> 00:09:42.270 align:start position:0% raid that thing because it's different 00:09:42.270 --> 00:09:43.970 align:start position:0% raid that thing because it's different to<00:09:42.420> have<00:09:42.570> a<00:09:42.630> five<00:09:42.900> star<00:09:43.170> with<00:09:43.410> two<00:09:43.590> persons 00:09:43.970 --> 00:09:43.980 align:start

have<00:09:45.000> five<00:09:45.210> stars<00:09:45.540> or<00:09:45.780> 4.8 00:09:46.430 --> 00:09:46.440 align:start position:0% rating it and have five stars or 4.8 00:09:46.440 --> 00:09:49.700 align:start position:0% rating it and have five stars or 4.8 having<00:09:47.100> 100<00:09:47.670> people<00:09:47.970> rating<00:09:48.300> it<00:09:48.420> right<00:09:48.710> but 00:09:49.700 --> 00:09:49.710 align:start position:0% having 100 people rating it right but 00:09:49.710 --> 00:09:52.370 align:start position:0% having 100 people rating it right but also<00:09:49.890> if<00:09:50.490> they<00:09:50.850> say<00:09:51.030> okay<00:09:51.300> maybe<00:09:51.930> you<00:09:52.110> need<00:09:52.260> the 00:09:52.370 --> 00:09:52.380 align:start position:0% also if they say okay maybe you need the 00:09:52.380 --> 00:09:54.470 align:start position:0% also if they say okay maybe you need the information<00:09:52.620> based<00:09:53.160> on<00:09:53.310> how<00:09:53.940> many<00:09:54.000> people 00:09:54.470 --> 00:09:54.480 align:start position:0% information based on how many people 00:09:54.480 --> 00:09:57.290 align:start position:0% information based on how many people choose<00:09:54.810> each<00:09:55.080> each<00:09:55.500> kind<00:09:55.980> of<00:09:56.130> rating<00:09:56.610> right<00:09:56.880> so 00:09:57.290 --> 00:09:57.300 align:start position:0% choose each each kind of rating right so 00:09:57.300 --> 00:09:59.480 align:start position:0% choose each each kind of rating right so they<00:09:57.420> put<00:09:57.540> it<00:09:57.660> this<00:09:57.900> histogram<00:09:58.350> so<00:09:59.190> you<00:09:59.250> can 00:09:59.480 --> 00:09:59.490 align:start position:0% they put it this histogram so you can 00:09:59.490 --> 00:10:03.500 align:start position:0% they put it this histogram so you can decide<00:09:59.640> it<00:10:00.470> well<00:10:01.470> and<00:10:01.680> after<00:10:01.860>

00:11:04.010 align:start position:0% to make this decision you need even use just<00:11:01.500> the<00:11:01.530> score<00:11:01.950> just<00:11:02.730> a<00:11:02.820> lot<00:11:03.000>
